2002 CHEVROLET SUBURBAN 2500 Engine And Engine Coolingengine Problems

WHILE DRIVING 60 MPH UNDER NORMAL CONDITIONS ON THE INTERSTATE, I EXPERIENCED FULL POWER LOSS. WITHOUT WARNING, THE ENGINE SHUT DOWN AND COULD NOT BE RESTARTED IN NEUTRAL. ENGINE TURNED, JUST DIDN'T FIRE. NO SPUTTER, NO DASH LIGHTS, JUST AN INSTANT SHUT DOWN. I PULLED THE VEHICLE TO THE SIDE OF THE ROADWAY, PUT IT IN PARK AND IT STARTED RIGHT UP.

STALLS OCCURED SEVERAL TIMES WHILE TOWING A 5000 POUND BOAT AND ALSO OCCURED WHILE TOWING A 9000 POUND CAMPER TRAILER. TWO DEALERS LOOKED AT THE VEHICLE AND REPORTED FINDING NO CAUSE FOR THE STALLING. I FOUND AN AUTOMOTIVE INTERNET DISCUSSION FORUM WHERE MANY OTHER PEOPLE REPORTED THE SAME PROBLEM WITH THE 8.1L ENGINE. MANY OF THESE PEOPLE REPORTED THAT THE CRANKSHAFT POSITION SENSOR WAS THE CAUSE, AND THAT REPLACING THE CRANKSHAFT POSITION SENSOR WOULD FIX THE PROBLEM.
